Genetic sequencing of severe mental illnesses in diverse populations

3/3 Sequencing and Trans-Diagnostic Phenotyping of Severe Mental Illness in Diverse Populations

NIH-funded research Cardiff University · NIH-11125799

This project will use large-scale genetic sequencing to find DNA changes linked to severe psychiatric conditions like schizophrenia, bipolar I, and serious depression in people from many regions.

What this research studies

You could take part in a global effort to sequence the protein-coding parts of the genome (whole-exome) and run genetic arrays on more than 150,000 people with severe psychiatric disorders alongside a similar number of controls. Clinical samples and information will be collected at collaborating sites across the Americas, Europe, Africa, and Asia, and a partner genomics center will perform the lab assays. Researchers will search for very rare exonic changes, copy-number differences, and common variants that may contribute to illness across diagnoses such as schizophrenia, schizoaffective disorder, bipolar I, and severe major depression. The project starts by using existing samples and then adds newly collected samples to reach its targets.

Who could benefit from this research

Good fit: Ideal participants are people with lifetime diagnoses of schizophrenia, schizoaffective disorder, bipolar I disorder, or severe major depressive disorder who can provide consent and a DNA sample.

Not a fit: People without these diagnoses would not be eligible and may not see direct benefits, and immediate clinical benefit is unlikely because genetic findings usually take time to translate into treatments.

Why it matters

Potential benefit: If successful, the work could point to biological causes of severe mental illnesses that over time lead to better diagnosis, new treatments, or clearer genetic risk information.

How similar studies have performed: Past large psychiatric genomics projects have found common risk variants, but this much larger, exome-focused and transdiagnostic sequencing effort is relatively novel and aims to find rarer, higher-impact variants.
